This work deals with the use of the Computational Fluid Dynamics (CFD) in coupled electromagnetic heating up processes. The CFD is based on solution of partial differential equations describing mathematically exactly a flow-area (Navier-Stokes equations) which link together fluid the velocity, pressure and enthalpy for flows. The undisputed advantage of the CFD method is its absolute independence of the Alfa coefficient for a thermal convection. This general knowledge of the thermodynamic field is applicable to sense critical areas of a simulated device or to its improvement. There are simulated two absolutely different applications for the complexity demonstration of the CFD method. The 1st simulation is a part of a switching station application and the 2nd is a simulation of a shrinking-on system for heating and connecting metal parts. The 1st simulation is calculated as a coupled problem of electromagnetic and thermodynamic fields. The 2nd simulation is calculated as a coupled problem of electromagnetic, thermodynamic and thermoelastic fields.A multiphysics software has to be used for a simulation of these different physical problems like the finite element method software ANSYS which was used in this work.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
